8uck5nort, If you havent already go to the hunting in western states forum and read posts about antelope hunting. Wyoming is your best bet as far as animal numbers, I have hunted the areas in the eastern plains 9, 10 ,12, 29 and there is some good state land, BLM land, and walk on private lands that you can find plenty of antelope on.
If you and your wife are looking to stay in a motel or something like that make your plans now as the few that are in the larger towns book up quick for hunting season and are hard to get.
If you dont mind paying a trespass fee, You should be able to find plenty of ranches that would allow you to hunt . You really dont need a outfitter unless you cant take care of the animal after shooting it, as that is a concern as early antelope season can be very warm and you need to get the animal cooled down quickly and out of the sun.
I live in OH and have gone to WY every year since 2000 and never tire of getting out there and seeing hundreds of square miles of open country with herds of antelope running around wild , sometimes seeing hundreds in a single day and only a handful of people that live there.
Antelope hunting is really fun as you never know what they will do next. Sometimes you really have to work to get within shooting distance of them and other times ( many ) I have had rutting bucks come right at me , barking, stiff legged within 40 yards and defy you to shoot them ?
If you go and are only after 1 animal, be sure the situation is what you want before shooting as it can be all over 5 mins into the hunt and your done, Been there and done that.
Good Luck and start making your plans now as the license draw for this year is already over but you can buy leftover licenses but need to read up and understand there system for licenses .
When they go on sale ( leftover licenses ) you can buy them online but they go quickly and you have to have a plan prior to know where your going to stay and what area you plan to hunt in.
Wish you the Best ! jedman
Update !! I just looked and the deadline for the antelope license draw is March 15 th so there is still a week left if you go that route.
